module ShouldCompile where
-- I bet this test is a mistake! From the layout it
-- looks as if 'test' takes three args, the latter two
-- of higher rank. But the parens around these args are
-- missing, so it parses as
-- test :: [a]
-- -> forall a. Ord a
-- => [b]
-- -> forall c. Num c
-- => [c]
-- -> [a]
--
-- But maybe that what was intended; I'm not sure
-- Anyway it should typecheck!
